Genes affected
CRPPA (HGNC:37276): (CDP-L-ribitol pyrophosphorylase A) This gene encodes a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase-like protein. Mutations in this gene are the cause of Walker-Warburg syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 12, 2023 | This variant has not been reported in the literature in individuals affected with ISPD-related conditions. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 473159). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu292Asnfs*3) in the ISPD gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ISPD are known to be pathogenic (PMID: 23288328). - |
